Linux with Active Directory authentication - how to automatically forward user's mail
 

Hello,

I have Linux servers set up to authenticate users from AD. Say user "joe" logs in, then a Unix user "joe" is created. When that user receives mail, it goes into his system mailbox. How can I configure my system so that when "joe" gets email, the mail is automatically forwarded to his email "joe.smith@ourdomain.com" ? I've looked at a few tutorials, and they require putting the specific user and their forwarding address in /etc/aliases. Is there a way to have the system automatically check if the user is an AD user, then send it to their correct email?

I'm using Centos 5.3, with Samba/winbind authentication against Active Directory, and procmail. I can use any other mail agent if necessary.

Thanks!

Sorry, I haven't used winbind but why are you creating unix users ? ... and why not have central home directories ?

I'm not creating users. More precisely, a local mailbox for the user is created. The user is defined in winbind.

.. sorry, this was a little misleading :)

You could configure your mail servers to use AD as an ldap source for looking up email recipients

Yes, that's what I don't know how to do.
